Kolinsky Sable Painting Brushes have long been recognized as the standard of excellence, a comparative benchmark of how other natural and synthetic watercolor painting brushes perform. Elite™ is a new synthetic-hair paint brush that is almost indistinguishable from natural Kolinsky. It is a challenge to see the difference. Aside from the more affordable price, it is the performance of this new synthetic hair paint brush technology that makes Princeton Elite™ the new standard for discerning watercolor painting artists.
